The common perception that people from other racial groups look alike is rooted in the way human brains process what they see, researchers say.

It has long been known that people find it easier to tell apart members of their own race than those of a different race. Now a new study backs up the idea that the phenomenon is rooted,at least in part,in visual andneuralprocesses.

The researchers, whose study has been published in the Proceedings of the National Academy of Sciences, reported how 20 white participants were shown a series of images including faces, numbers and objects, while they had their brains scanned using functional MRI—a technique that allowed the team to spot changes in activity.

In 19 of the 20 participants, a greater area of the face-recognition region was activated when the participants saw a white face compared with a black face. The researchers said that it suggested participants were better at picking up on physical differences between white faces—even for faces completely different to each other,brain activity was higher for white faces.

The researchers said the findings could help to investigate ways to avoid harmful biases. Nick Camp, the co-author of the research from Stanford University, said some evidence suggested the phenomenon could depend on which characteristics were used to group people.

Dr Holger Wiese, an expert in face recognition at the University of Durham in the UK who was not involved in the research,described the study as elegant. Hecautionedagainst linking the phenomenon to prejudice,noting it was not clear how or if it was tied in tostereotypes, which tended to be rooted in assuming personality or behaviors are universal within a group. He said,“We don't know whether what they describe here is the basis for racial prejudice—the paper doesn't say that at all.”
